According to a new report by In Touch Weekly magazine, Kim, 31, has been miserable since the public turned on her for filing for divorce — after 72 days of marriage — and now decided to take out all her misery on sister Khloe, 27.

While Khloe has been reportedly trying to help Kim cope, what she is getting in return from Kim are ugly verbal assaults. Kim’s feud with Khloe reportedly stems from jealousy because she cannot handle the fact that Khloe is happily married to Lamar Odomwhile her own marriage to her NBA player failed.

“Kim feels like her life is falling apart and she’s taking a lot out on Khloe,” a Kardashian insider tells In Touch Weekly. And what better way to hurt Khloe than to make fun of her appearance — something Khloe is reportedly sensitive about. “Kim told Khloe that Lamar is going to cheat on her if she keeps gaining weight,” reveals an insider.

In addition to that, Kim has also called Khloe “fat” to her face on more than one occasion while telling her she wouldn’t be famous if it wasn’t for Kim. And Kim wouldn’t be famous if it wasn’t for Ray J’s urine!

The insider insists that the recent fight on Kourtney and Kim Take New York was totally real, and that the two sisters “didn’t speak for weeks” as a result. During that fight, Kim called Khloe an “evil, ugly little troll,” though she later tweeted while the episode aired: “I’m sorry, KoKo! You know I love you soooo much! The things sisters do and say to each other.”

Khloe is now said to be firing back at Kimmie calling her a “bitch” at the recent Z100′s Jingle Ball concert in NYC when someone brought up her name.
